type conversion on boolean variables

[robinrossow]

hey,
I just encountered the problem that a boolean false got converted to the string "false" using your sanitize function:

console.log(typeof(worldhit));
> boolean
console.log(typeof(sanitizer.sanitize(worldhit)));
> string

the value of the variable is false and since !!"false" === true in javascript, it is always interpreted as true.

Similar problems happening for undefined variables. If I pass an undefined variable, it makes it string "undefined" and all my if(variable) checks afterwards became broken.

Working on a pull request.
